为了改进提高产品性能稳健性的工程设计方法,将稳健设计中的容差和所要达到的优质品率作为两个目标函数,建立了模糊稳健双目标优化设计模型,并应用物理规划方法进行求解。通过对齿轮传动装置装配尺寸链的稳健优化设计,给出了具体的分析求解过程。实例表明,该文所提出的方法是可行的。 In order to improve the engineering design method to improve the robustness of product performance, taking the tolerance in robust design and the high quality rate to be achieved as two objective functions, a fuzzy robust bi-objective optimization design model is established and solved by physical programming. Through the steady optimization design of the assembly dimension chain of gear transmission, the specific analysis and solving process is given. The examples show that the proposed method is feasible.
